A container comprising:

• a bowl, having a sidewall terminating in a rim;
• and
• a selectively detachable lid, said lid including:
• (i) a center panel;
• (ii) a peripheral sealing lip surrounding said panel, said peripheral sealing lip having a generally inverted U-shaped cross section so as to define a channel into which said bowl rim fits;
• and
• (iii) at least one ridge formed between said panel and said peripheral sealing lip, said ridge being interrupted by at least one vent opening, said ridge having a circumferential length that is greater than the circumferential length of said vent opening, wherein said ridge and said peripheral sealing lip at least partially overlap when viewed in a direction substantially normal to said panel, and wherein said ridge abuts the bowl rim when said lid is placed loosely on said bowl, and wherein said vent opening defines an air passageway between the bowl and ambient air when said lid rests loosely on the bowl such that the channel is substantially aligned with the bowl rim.
